Borescoped a .300 WSM barrel after something like 15 rounds of copper solids for load development.
Yowza...crazy copper fouling unlike I've ever seen.
Got to thinking about it, sure seems that solids will not deform/engrave into the rifling nearly as easily as jacketed lead.
Is it normal to see these "excessive" levels of copper fouling? Didn't see any pressure signs on the primers- but I expect that pressure profile is different with these as well.
